870 extractor help!

So, my dads brand new 870 is having problems 90% of the time extracting the spent shell. I have an 870 that's 10+ years old and has never had a single problem and I noticed something interesting.

On his (MIM) the extractor will rotate all the way past the side of the bolt. On mine (machined) the extractor hardly rotates back at all. I don't think it even rotates far enough to get past the rim on the shell.

So I put my machined one in his bolt and it acted the same as mine had... extractor will not rotate all the backwards. I ordered a volquartsen for his....and now it does the same thing as his orignal MIM one did!

Which way is correct?? How far should the extractor rotate???

The only way I was able to get his functioning was to stretch the extractor srping ~25% but this seems like a short term fix that won't last.
 
Here's the one on mine that has always worked.


and here's his new one that does this with both the factory and volquartsen extractor.
 
Just a follow up....

My dad called Remington and told them about all the issues the gun was having. They told him it was all caused by the barrel. He asked if he should send it in or what and they said, "no, throw it in the trash and we'll send a new one". He had a new barrel by the end of the week, and the gun now functions fine.
 
Yep, they had a run of barrels that had very rough chattered tooling marks in the chambers. For future reference...how far the extractor "rotates" backwards has nothing to do with how it extracts the spent hull. It only needs to go back far enough to jump over the rim of the hull. The effectiveness of the newer MIM parts is the same as the older machined ones. Fully machined parts might be less likely to break or crack over the life of the part, but I have never seen either happen to any of them.
 
Referencing MIM, I had the magazine catch on a Kimber 1911 crumble into pieces while firing it at the range. This was around the 750 round count mark. I used a tool steel heat treated Ed Brown part to replace it.

That's what I figured with the extractor rotation but wasn't really positive and it was the only thing I could visually find that was different. He also polished the chamber in the original barrel and it didn't fix any of the problems. But yes, the tooling marks were horrible. The original barrel also had absolutely brutal recoil. I ran my SPS SM for 10 years and never thought it was bad. His 870 barrel with 2 3/4 target loads was comparable to a 3 1/2 goose load out of my maxus. Whatever was wrong with that barrel was seriously wrong.
 
Good to see the customer service. I have an old one that wore out and had to replace it with the volq. extractor and its humming along like new now.
 
I bought a 870 Wingmaster Super Mag years ago but only put about a box of shells through it when it started failing to extract any round out of the chamber. I called Remington and they said since it was over a year old they wouldn't warranty it. I sent it to them and $160 later they replaced the extractor. I read this was a common problem. Will never buy Remington again. All my older model 870's are fine, newer ones not so much.
